Abstract

A new cyprinid species, Garra kalpangi is described from the Kalpangi River (Brahmaputra basin) in Arunachal Pradesh, India. The species is closely similar to G. gravelyi, G. rotundinasus and G. elongata in having a shared character i.e. a weakly developed proboscis. It is distinguishable from G. gravelyi for the absence of indistinct black spot at the bases of branched dorsal fin rays and lateral stripes on the side of the body. However, G. rotundinasus possesses lateral stripe along the lateral line. Further, the absence of transverse groove at the tip of snout and longitudinal black band in medial coudal fin differentiated it from G. elongata. The detail comparative account of the 16 available species of northeastern India confirmed its distinct diagnosis as a new species under the genus. Accordingly, after thorough investigation, the taxonomic keys for all the available species under the genus from the region have also been erected in this article.
